G-L-A-M.... Ok you get the point. Grammy Award Winning Fergie graces the cover of the May 2008 issue of Glamour Magazine. 

In the interview, Fergie speaks candidly about her engagement to drop-dead-gorgeous Josh Duhamel, getting pregnant, and dealing with "fat days".

GLAMOUR: As an entertainer, your body is a part of your business. Is that stressful, or does it help keep you motivated?

FERGIE: It's a good thing; I like to keep myself in check. Because everybody goes overboard once in a while. I learned a lot of lessons. A lot. Just by...

GLAMOUR: ...eating too much?

FERGIE: Doing everything too much! But I have learned more and more to enjoy my body when I have a few extra pounds on, just being more voluptuous.

GLAMOUR: Do you ever have fat days?

FERGIE: You just have to know what looks good on you. I say, focus on the body part that you feel most comfortable about. My legs don't change much so a good look for me is a short black dress with long sleeves. If you see me in that, you know I've gained a few pounds, which is fine.

GLAMOUR: That's good advice. Health-wise, is there anything else you do?

FERGIE: I do vinegar shots. It has to be organic apple cider, unfiltered.

GLAMOUR: You do a shot of it?

FERGIE: Two tablespoons. For some reason I've noticed a difference on my stomach. I just trusted [my trainer] on this one. I'm sharing. I'm all about sharing secrets. [Fergie's trainer, Natasha Kufa, told Glamour that she believes vinegar shots flush out fats in the colon, which helps the body digest food and gets rid of cravings.] [Glamour]
